Hello I’m a Linux newbie and I need some help. I’m running fedora on my laptop and I want to connect my Logitech mouse. I got solaar installed but I need to manually install the udev rule. I’m following the Instructions here
So I understand that I need to copy rules.d/42-logitech-unify-permissions.rules from the solaar GitHub and place it in /etc/udev/rules.d the thing I don’t know how to do is get there. I’m not super familiar with the terminal
Edit : adding this for any future people having the same issue. I booted up my wife’s old windows 10 PC, downloaded Logitech unifying software and re-paired the mouse and dongle. Put the dongle back into my Linux PC and the mouse is working. Weirdly though solaar still shows nothing but an empty window. But whatever at least the mouse is working.
Edit 2 : just figured out if I open terminal and type sudo solaar it opens solaar and my devices show up. If I just open it from the start menu or don’t use sudo in the terminal solaar opens an empty window.


I did install it through the package manager. For some reason though my Logitech mouse doesn’t come up on solaar. When I was looking for a reason I found something about the udev and thought that’s what I had to do, I didn’t realize I was reading mac stuff 😅
I had issues with Solaar detecting my devices when plugging the dongle in a USB hub in the past, even when the connected devices worked. Maybe you can try to connect the dongle to another port, in best case directly on the Notebook or PC mainboard, just to make sure that this is not the issue.
This being said, it works for me on even with a USB hub on a freshly installed Fedora on a new PC.
Interesting, Im starting to think it might just be the hardware. It was sitting unused for a year or two. I’m gonna see if I can find a windows PC to plug it into just to see if it is indeed the hardware. I already tried it on every port and on my other PC running bazzite but had the same thing happen.
First time installing solaar last week. Was from package manager on Trisquel(deb based).
All installed and detected automatically. Probably the same under Fedora.
Try a purge/uninstall of solaar, and then put the dongle in before you reinstall.
(Random aside. If your PC auto-resumes after suspend, it may have picked up a logitech keyboard from another room. Unpair it from your dongle)
Tried those things, no luck. And no other Logitech things around to connect too. I’m starting to think it might just be a hardware issue. It’s a mouse and keyboard I haven’t used for a while.
I’d try:
I honestly don’t know much about terminal, how could I go about doing that? I’m pretty sure this is exactly my problem. I had stumbled on this Reddit thread when looking for a solution. But someone here pointed out that the link lsd_ninja provided was for MAC so I thought I must’ve been on the wrong track. I know I have to copy the file from the GitHub. I just don’t know how to get to the location where it goes.
